We know that Bittrex and Poloniex are the most sought after exchangers.
But I want to know which one is best to trade? and I want to know why.
Thanks.

I was using Poloniex before, but when the times come that poloniex faced some controversial issues I decided to transfer all my accounts in Poloniex into Bittrex. And I know most the Poloniex users slaos shifted into Bittrex too.
